"This invention relates to mfli'qfi iail handling apparatusand morepartioularlyto stock trays of the type used on trucks for storing andtransporting relatively wide strips of uncured or partially cured rubberin the manufacture of vehicle tires. The invention is, however,applicable to other types of material handling equipment in which itisrdesired to dispose a number of pieces or strips .of relatively widestock in prqgimityto buttseparated fromone another. I

It is an object of the invention to provide a generally improved stocktray incorporating separating means which permit a plnrality of stripsor adhe i e o taqk s c t bedispo ejd on the ili yyin overlapped relationwith respect to one eat e nqt co asta A o hs 'i bi i'sjt p ovide a stoct y h ving a relatively rigid separator movably in'o nted so that inloading and unloading the tray the separator can be readily shifted intoand out of separating position. More specifically, the inventiqncontemplates a separator in the form of a pivoted-leaf which-is swunginto and out of overlapping relation with respect to a strip ofrubber orother tacky stock disposed on the tray.

Other objects and advantages will become apparent as the descriptionproceeds'and v relate to details of constructionand arrangements ofparts for obtaining a simpleand .inexpensivetseparator designthat can,be readily manufactured and installed.- The des'criptionismade inconnection with the aecompanyingvdrawings :forming a part of thespecification; "Like parts throughout the several vlews are ;indicatedby the same letters and numeralsiof reference.

Desirably the notches l8 are above thelevel of the corresponding pivots I so that a slight liftingforce orcouple is exerted on each of the trays even when the latter are in theirlowered or Each tray is used to carry a plurality of stock stripsindicated in the drawings at S-l and S2, the stock'being centrallythickened in cross sec-' tion and used in the manufacture of pneumaticvehicle tires. The adjacent relatively thin edges 2! and 22,respectively, of the stock strips are overlapped and separated from oneanother by a shiftable leaf or panel B formed of a relatively stiff,rigid, or shape retaining material such as composition board, plywood,or sheet metal. The separator is fastened along one longitudinal edge tothe tray apron II by hinges 24 which permit the leaf to be swung backand forth to overlie different portions of the apron I I as indicated bythe broken and solid lines of Fig. 4.

' In loading each of the trays A the separator Pateiltof the UnitedStates is:

Ida stock truck of the type having a supportingstructure and aplurality of superposed elongated trays mounted thereon and movablerelative to one another in loading and unloading the truck, a separatoron each tray comprising a substantially rigid leaf of greater lengththan width, each of said leaves being hingedalong one side edge to thetray for swinging movement about an axis parallel to the long axis ofsuch tray, and the hinge axis ofeach separator leaf being disposedso'that in one position the separator leaf is disposed wholly on oneside of the longitudinal center -line'of the tray and in anotherposition 5 the leaf overliessuchlongitudinalcenter line of leaf B isswung or shifted to the full line position T single separator leaf, asillustrated, the leaf is located with the line 26 of the hinges 24 oifcenter or spaced away from the hinged side of the tray a distancegreater than half the tray width; Swinging or moving the separator leaffrom the full line position of Fig. 4 in which it lies wholly on one orthe outside of tray center line 25, to the full line position shown inFig. 3, in which it overlies the marginal side portion 2! of. the stripS-|, shift the leaf separator to a central position along the length ofthe tray, approximately midway between the side members 8 and 9 of thelatter. The strip S-2 is then placed on the outer portion of the trayapron II, the edge portion 22 of the strip resting upon the leafB andbeing separated thereby from the edge portion 21' of the strip Sl Onlythe relatively thin edge portions of the stock strips are over-'-lapped, the leaf separators not extending'over the thick central portionof the stock and being disposedbetween the thin edges only of thestock.

In unloading the truck trays the procedure is reversed; from each traythe strip 8-2 is first removed, the leaf B is shifted or pivoted awayfrom the side portion 2| of the strip S-l, and the latter is then liftedfrom the tray.
